TheAnalysisoftheunit
本单元的中心话题为“拯救地球”,通过课堂导入引出水污染、空气污染、环境破坏,乱砍乱伐树木等环境问题,围绕这一主题,结合听、说、读、写的训练达到熟悉话题表述,语言熟练应用,能运用所学知识就环境问题展开讨论,在口头上和笔头上阐述自己的观点,达到语言输出的目的。
“热身”(Warmingup)部分,运用图片导入法,通过对所展示图片的讨论,引出环境保护、拯救地球的主题,初步了解学生对现状、原因、解决办法的掌握程度,并通过提问了解学生对本单元学习内容、学习策略、学习途径的愿望,以便教师及时调整其后课堂教学的内容、难度、和深度的把握。
“听力”训练由两大部分组成,分别安排在“听力”(Listening)和“综合技能”(IntegratingSkills)两个部分。
前者又由两部分组成,第一部分为纪念“世界地球日”活动上的讲话,阐述了保护水资源的必要性和紧迫性。
第二部分围绕保护水资源的主题,介绍了如何保护水资源的具体措施;后者,作为综合语言运用部分,听力内容主要为其后的写作作为铺垫,除了敏锐捕捉语言信息以外,学生还需要了解发言稿的开篇、论证、以及结束。
“阅读”(Reading)着重介绍世界地球峰会的由来,详细描述了2002年南非约翰内斯堡地球峰会的召开情况,展示了“可持续发展”这一主题,会上大多数代表所涉及的“世界三大杀手(被污染了的饮用水、简陋的卫生设备和空气污染,以及贫困、战争、和暴乱,指出世界的顺利发展,取决于各国的和平相处、互相合作、互相促进、共同进步,最后文章还阐述了世界地球峰会的作用和意义。
“语言学习”(LanguageStudy)要求学生利用构词法的知识,灵活运用词形变化进行正确运用,在第二部分要求学生正确辨别-ly结尾词的词性。
“语法”(Grammar)通过对倒装形式的总结,全面了解倒装的具体结构和应用,结合句型转换和选词填空练习,帮助学生掌握这一语法现象。
“综合技能”(Integratingskills)采用高一课本中未曾出现过的展示方式,选用听力方式展示写作模式,通过口头讨论等方式,巩固学生对本单元知识的掌握,从而有效地指导学生进行写作练习,并通过Unit2中的checklist对所写的书面表达进行修改。
